Solution Overview

Problem

Existing amusement ride speed trim systems face challenges in quickly and reliably reducing the speed of passenger vehicles due to mechanical interference and friction issues in guide systems, particularly with eddy-current braking devices.

Innovation Solution

A speed trim system featuring a magnet arrangement on the passenger vehicle and a trim brake along the track with a pivotable induction blade supported by a pneumatic cylinder, allowing for precise and rapid adjustment of braking force by pivoting the induction blade between active and inactive positions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If eddy-current braking devices with movable magnet arrays are used for speed trimming, then braking force can be adjusted, but mechanical interference and friction in the guide system prevent quick and reliable speed reduction

Engineering Contradiction:
Improvespeed trimming reliabilityVSAvoidguide system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Instead of moving the magnet arrays along the track to adjust braking force, the patent inverts the approach by keeping magnets stationary on the track and moving the induction body (fin-like structure) attached to the vehicle. This eliminates the need for complex guide systems to position magnets while still achieving variable braking force through the relative motion between magnets and induction body.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent replaces the mechanical guide system required for moving magnet arrays with an electromagnetic interaction system. The braking force is controlled by the relative motion between stationary magnets and the vehicle-mounted induction body, eliminating mechanical friction and interference in the guide system while maintaining reliable speed trimming capability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If magnet arrays are displaced to adjust braking force, then speed trimming is possible, but magnetic force between arrays pushes magnets toward equilibrium, reducing control precision

Engineering Contradiction:
Improvebraking force adjustmentVSAvoidspeed control precision
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent inverts the traditional eddy-current brake configuration by placing magnets on the stationary track and the induction body on the moving vehicle. This eliminates the problem of magnetic forces pushing movable magnets toward equilibrium, as the magnets remain fixed in position while the induction body moves with the vehicle, providing precise and stable speed control.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The system uses the vehicle's own motion to create the relative movement between magnets and induction body. The braking force is automatically adjusted according to the vehicle's speed through the interaction between stationary magnets and the moving induction body, eliminating the need for active displacement control of magnets while maintaining precise speed regulation.

Inventive Principle:
Principle #25Self-service

3Ease of manufacture

If friction brakes are used for speed reduction, then simple construction is achieved, but mechanical interference and wear reduce reliability and increase maintenance

Engineering Contradiction:
Improvebrake system constructionVSAvoidbrake system reliability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent replaces friction-based mechanical brakes with an eddy-current braking system using stationary magnets and a vehicle-mounted induction body. This eliminates direct mechanical contact and friction between brake components, significantly reducing wear and improving reliability while maintaining relatively simple construction. The braking force is generated through electromagnetic induction rather than mechanical friction.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
